摘要

To develop high emissivity coatings on fibrous ceramic substrates with improved thermal resistance for reusable space systems, WSi₂–MoSi₂–Si–SiB₆-borosilicate glass coatings were prepared on fibrous ZrO₂ by slurry dipping and subsequent high temperature rapid sintering. A coating with 20 wt% WSi₂ and 50 wt% MoSi₂ presents optimal thermal stability with only 10.06 mg/cm² mass loss and 4.0% emissivity decrease in the wavelength regime 1.27–1.73 μm after 50 h oxidation at 1773 K. The advantages of double phase metal-silicide coatings combining WSi₂ and MoSi₂ include improved thermal compatibility with the substrate and an enhanced glass-mediated self-healing ability.
